Hello,
I am new to NI hardware and am having problems with my PCIE 6343. I have the card hooked up to 2x TBX-68 breakouts.
In the NI Max Test panels, all analog inputs read -10.8volts
In my test setup I have the wiper of a potentiometer connected to AI0+ (pin68). The other two potentiometer connections are at +5v(pin14) and AI Gnd(pin32). AI0-(pin34) is connected to AI GND as well. With a multi meter, I can measure varying voltage potentials on the screw terminal of AI0+. But the test panels, and the Voltage Task read -10.8volts with no deviation from that number.
I have also tried a K type thermocouple, wired as per the connection diagram, on more than one port and the test panels consistently read -2.*** volts
My card resets normally, and passes the self test. Also I have verified the functionality of the 4 analog outputs (two on each TBX-68) which allowed me to rule out my cables or breakouts as the source of the problem and let me verify my understanding of the TBX-68s.
Any help would be greatly appreciated.

A wiring diagram and screenshots of the signals you are receiving would be helpful for troubleshooting

Here is a bit of info and a few screenshots that illustrate my setup / issue

I am unable to self calibrate this card. It is asking that I externally calibrate it. Is poor calibration something that could create the kind of results I am getting. All analog inputs measure -10.8volts.
Is there any kind of test that would verify that my analog inputs are functional?
